BERTH.

SPECIFICATION forming part of Letters Patent No. 622,993, dated April11, 1899.

Application filed November '7, 1898. Serial No. 695,769. (No model.)

T0 on whom it may concern:

Be it known that I, ARTH R NEVILLE CHAMBERLAIN, a subject of the Queenof Great Britain, residing at I'Iighbury, Moorgreen, in the county ofWorcester, England, have invented certain new and useful ImprovementsinBerths, of which the following is a full, clear, and exactspecification;

This invention has relation to collapsible or shut-up sleeping-berthsfor ships and analogous purposes, also to collapsible bedsteads andcots, and has reference primarily to ships sleeping-berths of thattypewhich are arranged in blocks or'tiers and supported by uprights disposedin series of ranks adapted to be collapsed or closed together insuccession for folding up the berths, and also of being extendedindividually and in succession when required for use, and also in whichthe berth-frames themselves are, employed for bracing together the saiduprights and preserving their parallelism both when collapsed and whenextended.

The present invention consistsin a newconstruction of such berths inwhich the rectangular berth-frames adapted to support the bedding areprovided at the extreme ends of their sides with outstanding androllered studs confined and working Within vertical races carried by theuprights and with the said frames supported and partly balanced by beingpivotally hung from radius linksor bars also carried by the saiduprights.

Figure 1 of the accompanying drawingsrepresents an end elevation of acollapsible sleeping-berth constructed according to this invention andshown distended or in position for use. Fig. 2 is another end View, butshowing the parts in the positions they assume when the berth is closedor collapsed. Fig. 3 is a front elevation of Fig. 1. Fig. 4 represents,upon an enlarged scale, an elevation of the upper part of one end of theberth. In this view the parts are represented in full lines in theirextended positions,while the dotted lines represent the same partiallycollapsed. Fig. 5 represents an end elevation of a block of three berthsembodying these improvements, one of the said berths being showncollapsed and the other two extended.

The same letters of reference indicate corresponding parts in theseveral figures of the drawings.

In the arrangement shown each pair of berth-bottoms a a are disposed intiers one above another and are supported by a series of pillars b insuch a manner that each series of four comprehends a rectangular spacewithin which the tier of two berths-frames are placed one above another.The inner and opposite edges or sides of the supports are provided withvertical races. or slots b 19 each of an inside range a little greaterthan one-half the breadth of the berth-frame and with the races 1) uponthe one post of each pair coming above the plane of the berth-frame,while the race 19 on the opposite post comes below it. The ends a of theberth-frame have at the opposite corners a a journaled or rollered studsor a which respectively engage and run within the upper and underraces 1) b and in the extended position the stud of at the one side ofthe frame end comes at thebottom of the one race I), while the otherstud 0. comes at the top of the race b on the opposite post. Therectangular berth-frame is also pivotally hung from a pair of radiuslinks or arms 0, whose upper ends 0 are jointedly connected or pivotedat c to those pillars or supports to which the races Z) are fitted. Theseries of four uprights is thus cross-braced by the pairof berth-frames,which are themselves kept in place by the races and balanced by beingsuspended near their middles from the swinging radius-links, asaforesaid. A block or row of berths to any desired number may be made upby duplicating or multiplying this arrangement, as shown in Fig. 5,audit is understood that the foot ends of the uprights are provid edwith runners or rollers e, which run upon the deck, and that when it isrequired to collapse the berth-frames they are given a revolving motionaround theends of the radius-bars as pivots, which causes the pillars toapproach one another or col1apse,while preserving their parallelism. Theberth-frames then fall into nearly vertical positions .(see Fig. 2)parallel with but intermediate between the uprights, the ranks ofwhichare collapsed into juxtaposition with one another. It is also proposedthat the ends of the several berths of a tier should be verticallybraced by tie-bars d, which may have eyes taking onto the journalends ofthe frames, which are thus caused to move rigidly and in unison. Thesebars may be provided with pulls d, whichconveniently are taken hold offor collapsing-or extending the articulated structure.

Having fully described my invention, what I desire to claim and secureby Letters Patent 1s 1. The combination in'folding berths of two or moreberth-frames one above another, uprights or pillars between which theframes are arranged, those upon one side having vertical races extendingbelow, and the uprights on the other side having similar races extend.-ing above-the frame the ends of which are provided with outstandingstuds to move in said races, and radius-bars jointed to the end bars ofthe frame and to the uprights on one side, substantially as described.

2. In folding berths the combination with two or more berth-framesarranged one above another of a series of uprights or pillars arrangedat the angles of said frames, those upon one side having vertical racesextending below the frames and those upon the other side having similarraces extending above the same to receive studs on the ends of saidframes, radius-bars jointed to the end bars of said frames and to theuprights having races extending below them, and tie-bars having eyes toconnect them to the studs, substan tially asdescribed.

3. In a folding berth, the combination with a rectangular berth-frame,of uprights or pil-.

lars arranged at the four angles of said frame, those upon one sidehaving vertical races extending below and those on the other side havingsimilar races extending above the frames to receive outstanding studs onthe end bars of the latter, and radius-bars having their ends jointedabove the berth to the uprights
